Default Oh gawd another I need help with tuning thread!!

So folks here's the skinny
2017 GT Performance Package
Amr long tube headers
Off road x pipe
Corsa cat back
Gt 350 throttle body
Gt 350 intake manifold
Pmas tune required cold air
Sctx4 tuner
I took the car to Travis over at Gearheads over in Arlington, TX (most of you that doesn't mean much). After repeated attempts to tune the car still continues to have issues at partial throttle. At wide open it seems to run pretty good it dyno'd once at 432 under high temp and high humidity and the next time on a cooler lower humidity day he got 440+. I didn't see that one or a dyno sheet but I chalk that up to weather conditions anyhow.
Was wondering if any of you good people have the same or similar setup and if you've had problems.
I should also note he has tried putting the stock throttle body back on and says that he thinks the gt 350 tb ran better but still the daily drivability is garbage. I'd rather go back to stock completely if it's going to surge (wooom wooom wooom) or have a dead pedal till 2k rpms.
Insights or advice greatly appreciated and thank you all in advance.
